Last week, three prominent neurosurgeons told the CNN interviewer Larry King that they did not hold cellphones next to their ears. â€œI think the safe practice,â€ said Dr. Keith Black, a surgeon at Cedars-Sinai Medical Center in Los Angeles, â€œis to use an earpiece so you keep the microwave antenna away from your brain.â€
These are people that operate on brains.Â They are not experts on things that cause cancer.Â Their opinions should carry little more weight than any reasonably educated person you pull off the street, which is to say very little.Â Â They do get this right:
Cellphones emit non-ionizing radiation, waves of energy that are too weak to break chemical bonds or to set off the DNA damage known to cause cancer. There is no known biological mechanism to explain how non-ionizing radiation might lead to cancer.
That is pretty much it, end of story.Â Basically, cell phones use a weak microwave transceivers to get signals to and from a cell tower.Â If microwaves cause cancer, we’re doomed, because they are all around us, all the time.Â Cell phone transmit microwaves at fractions of a watt.Â A typical civilian marine radar transmits microwaves at 4000 watts of power.Â Yet you don’t typically hear concerns about fishermen getting cancer from the boat’s radar unit, or people living near airports getting their brains cooked by the tower’s radar dish, which is even more powerful.
